Chapter 5 Serial Functions

When serial interface 0 is used for simultaneous transmission and reception, set the SCnCE0 and SCnCE1 flags of the SCnMD0 register to "00" or "01", so that the reception data input edge is opposite in polarity to the transmit data output edge. Also, the polarity of the reception data input edge is opposite polarity of the transmit data output edge of the other device.

SBT0

Data is input in synchronization with the rising edge of the clock.

SBI0

Data is output in synchronization with the falling edge of the clock.
